Unfortunately, I Really Am That Nerdy

Well, I've gotten my first version of the RetrievalBot complete. It's a track-chassis Roverbot (one of the basics in the Lego Mindstorms Constructopedia) with a single bumper on the back, and a homebrew odd spring-ish arm.

Behind or on top, yes. I've actually had to redo most of the arm arrangement already, as it tended to pull itself apart as expected; I had to set it up using two 3x1 boards with holes and a z24 gear with holes, and two extended black pins- it works better that way.

And hands just aren't as much fun. But if you want "complicated," get a Rube Goldberg machine.

Pity that most Rube Goldberg machines involve things that aren't as likely to stay put, though- such as something involving a fishbowl and an irritable bulldog, that sort of thing. Otherwise I'd have them all over the house. :)
